Hey guys.

after 11 mags or so with CO2, I found some cracks (or mor like small white line) on the lower receiver. When I did my bolt stop modification (see previous posts) I also put in 2 screw to hold the PVC block in place. one on each side. I found out that this screw was acting like a hindge and applying the recoil force downward forcing the corner of the block to "open" the lower receiver. Hence, the small white lines. (I'll post pictures tonight so you guys can understand better). I then decided to fill the bottom of the block with hot glue. Hot glue is like a shock absorber. I shot maybe like 15 more mags and now it seems to be ok. When I have more free time I will add 2 more screws.

Now for mags problems. I have 5 CO2 mags. 3 are working good. 1 is completely new and useless. As soon as I screw the cardridge in it it all empty by the striker valve. The other one is slowly leaking. I tryied to use silicon oil on the orings but it did not helped me. Now I'm hunting for another type of oring. Maybe a softer type to help seat better...

If you guys have any idea or experience please let me know. I'll keep you updated on how my search turn out...
